Research Institution
65526 Current and next generation experiments in nuclear and particle physics require detectors with high spatial resolution, fast response, and accurate energy information. However, in many nuclear physics experiments, the existing detector technology is the limiting factor. This project will develop a position-sensitive silicon avalanche photodiode that can be produced in large area at low cost and has excellent position, timing, and energy resolution. In Phase I, position-sensitive avalanche photodiodes were fabricated in two designs. These devices showed very high position and timing resolution, along with good energy resolution. Based on the results, the feasibility of the proposed approach was adequately demonstrated. During Phase II, large area, position-sensitive avalanche photodiodes will be produced and evaluated to assess their performance for nuclear physics studies as well as other applications. Commercial Applications and Other Benefits as described by the awardee: In addition to uses in nuclear physics studies, the new detectors should be applicable to medical imaging, NDE geological exploration, industrial CT imaging, X-ray instrumentation, space physics, and materials analysis.
